1/2" irrigation pipe

This is the pipe I used for all the connections. You might have to search around to find 100' instead of 200' (but trust me, you'll end up using a lot of this when you want to run the water to the garden etc.)

1/2" Forstner bit

(Be sure to use a forstner bit which will center the hole and make a clean hole.)

(this one will require a bigger drill chuck:)

The tap tool

(Use this to thread a hole in the barrel - "Tap a barrel")

Teflon

(this is the liquid teflon which seals the threads in the barrel - no leaks!)

1/2" threaded coupling

(Use this to tap into a barrel. You need 3 per stack of barrels.)

Tee connector

(Use 1 of these to connect the barrels at the bottom - use an elbow for a the barrel at the end. This will be explained on the next page.)
